4 Claims. (Cl. 100295) This invention relates to a device to be used in securing together bundles particularly of elongated metallic ingots or rods having square or rectangular cross section. The device of this invention in addition to functioning as a securing device is so designed to provide a pallet base or skid for such bundles of ingots or rods to permit convenient transportation and stacking or tiering of the strapped bundles.

The device of this invention will be apparent from the following description and the annexed drawing in which:

Fig. 1 illustrates a general side view of the device of this invention.

Fig. 2 illustrates a vertical cross section of the device taken along the lines 22 of Fig. 1.

Fig. 3 illustrates a horizontal cross section of the device taken along the lines 33 of Fig. 1.

Fig. 4 illustrates a detail of frame of the device of this invention.

Fig. 5 illustrates how the device is used to secure bundles of metal bars together and its application in stacking or tiering the same.

Referring now particularly to Figs. 1, 2 and 3, the device of this invention comprises a generally rectangular end plate 11 which is characterized by provision of a centrally cut out vertical channel 12. The metal forming the base of the channel is therefore of less thickness than that forming the remainder of the end plate. Preferably, the channel is also provided with elongated slots 13 for reasons which will hereinafter be described in more detail. Surrounding the end plate 11 is a projecting frame 14. This frame is provided with, in the center of its top member, an upstanding arcuate portion 15 substantially as shown. The frame projects from the face of the end plate and the inner edge of the frame is beveled or chamfered as at 16. Corner pieces 17 are provided at the lower corners of the frame as illustrated more particularly in Fig. 4. If desired, particularly for the purpose of reducing weight, the end piece 11 may be perforated as at 18.

Extending below the frame and end plate is base 19 which is longitudinally centrally divided. Preferably the center of the base 19 is provided with an arcuate cutout portion 19:: of a size greater than the arcuate portion of the top of the frame hereinbefore described. The bottom surface of the base 19 is characterized by the provision of gripping means preferably in the form of serrations 29 which project outwardly and downwardly. Conveniently, the side members of the base portion may be composed of downward extensions of the side frame members.

Operation of the device of this invention will become clear from Fig. 5 in which is shown bundles of ingots 21 secured together by means of one of the devices of this invention at each end of the bundle. Provision of the beveled inner edge of the frame of the securing device permits the device to be firmly wedged over the end of a bundle of rods. The slotted central channel in the end plate provides a weaker cross section portion which permits some lateral stretching of the device during pressing over the end of a bundle of rods. The arcuate center of the top frame member 15 also permits some expansion of the frame. As will be noted in Fig. 5, bundles of ingots and rods which have been secured by employment of the device of this invention may be readily tiered or stacked since the upstanding arcuate portion of the top frame member will nest into the arcuate cut-out portion in the base of another frame. The top member arcuate portion 19:: also provides a convenient ring or lifting means for handling the secured bundle. The rods are secured firmly in position in the frames with additional support provided by the extending corner pieces as de scribed without the necessity for employing additional binding or strapping means as will be apparent from Fig. 5 of the drawing.

Provision of the skid portion of the device elevates the bundle proper above the supporting floor so that it can readily be transported for instance by means of a forked truck or other conventional device. The divided base member provided with gripping means on the bottom surface is effective in maintaining the bundle so secured without shifting or sliding. In the preferred embodiment described and illustrated, the downwardly and outwardly projecting serrations tend to dig into'the supporting surface. The divided base provides a central weakness point so that weight and shock imparted by the bundle load will act to tend to depress the center of the base rather than the outside thereof resulting in effective digging in of the downwardly and outwardly projecting serrations.

It is preferred to fabricate the bundle securing and skid device of this invention entirely of metal and particularly of the same alloy as that forming the ingots or bars in the bundle. The unitary design of the device of the present invention is readily adapted for manufacture by a simple casting operation, for instance by die casting. After shipment of the bundle, both the material of the bundle and of the secured and skid device, may be utilized and no waste strapping or supporting materials are employed and no foreign strap or pallet materials are present to accidentally contaminate the shipment.

While this invention has been described and illustrated by the embodiment shown, it is not intended to be strictly limited thereto and other modifications and variations may be employed within the scope of the following claims.

I claim:

1. A bundle securing and skid device comprising a generally rectangular end plate having a vertical central channel formed therein, a projecting frame surrounding said end plate, said frame having a central, arcuate upstanding portion at the top thereof, and having a beveled inner edge, and a centrally divided base extending below said frame having gripping means on the bottom surface thereof.

2. A bundle securing and skid device comprising a generally rectangular end plate having a vertical central channel formed therein, a projecting frame surrounding said end plate, said frame having a central, arcuate upstanding portion at the top thereof, and having a beveled inner edge, projecting corner pieces at the bottom cornets of said frame, and a centrally divided base extending below said frame having gripping means on the bottom surface thereof.

3. A bundle securing and skid device comprising a generally rectangular end plate having a vertical central channel formed therein, a projecting frame surrounding said end plate, said frame having a central, arcuate upstanding portion at the top thereof, a beveled inner edge, and a centrally divided base having a central arcuate cutout portion of a radius greater than the radius of the upstanding portion at the top of the frame extending below said frame, said base having gripping means on the bottom surface thereof.

4. A bundle securing and skid device comprising a generally rectangular end plate having a vertical central channel formed therein, a projecting frame surrounding said end plate, said frame having a central, arcuate upstanding portion at the top thereof, and having a beveled inner edge, and a centrally divided base extending below said frame having outwardly and downwardly projecting serrations on the bottom surface thereof.
